Description
Ammonium polyphosphate (APP) is a kind of high quality, highly effective, non-toxic inorganic flame retardant, fire
retardant coating is all sorts of inflating and flame retardant products will add fire retardant additives.
Ammonium polyphosphate is widely applied in the expansion type fire retardant coating, polyethylene,
polypropylene, polyurethane, epoxy resin, rubber, fiber board and dry powder, etc., is a safe effective phosphorus
is non halogen flame retardant smoke elimination.
Ammonium polyphosphate in polyurethane hard foam has a high flame retardant, dimensional stability, hydrolytic
resistance and heat resistance.For rigid polyurethane foam plastics toxic and corrosive gas generation, and even
can be comparable to similar non flame retardant material.Of carbon monoxide and hydrogen generation is much
lower than the halogen containing polyurethane foam plastics.
